Frédéric
Joliot – Biography

Jean Frédéric Joliot, born in Paris,
March 19, 1900, was a graduate of the Ecole de Physique et Chimie of the city
of Paris. His father was Henri Joliot, a merchant, and his mother was Emilie
Roederer. In 1925 he became, at the Radium Institute, assistant to Marie Curie,
whose daughter Iréne he married in 1926. He obtained his Doctor of Science
degree in 1930, having prepared a thesis on the electrochemistry of radio-elements,
and became lecturer in the Paris Faculty of Science in 1935. At this time he
carried out considerable research on the structure of the atom, generally in
collaboration with his wife, Iréne Joliot-Curie. In particular they worked
on the projection of nuclei, which was an essential step in the discovery of
the neutron (Chadwick, 1932) and the positron (Anderson, 1932). However, their
greatest discovery was artificial radioactivity (1934). By bombardment of boron,
aluminium, and magnesium with alpha particles, they produced the isotope 13
of nitrogen, the isotope 30 of phosphorus and, simultaneously, the isotopes
27 of silicon and 28 of aluminium. These elements, not found naturally, decompose
spontaneously, with a more or less long period, by emission of positive or negative
electrons. It was for this very important discovery that these two physicists
received in 1935 the Nobel Prize for Chemistry. During this time F. Joliot,
who had always taken an interest in social questions, joined the Socialist Party,
the S.F.I.O. (1934), then the League for the Rights of Man (1936)

In 1937 he was nominated Professor at the Collège de France. He left
the Radium Institute and had built for his new laboratory of nuclear chemistry
the first cyclotron in Western Europe. After the discovery of the fission of
the uranium nucleus, he produced a physical roof of the phenomenon; then with
Hans Halban and Lev Kowarski, joined by Francis Perrin, he worked on chain reactions
and the requirements for the successful construction of an atomic pile using
uranium and heavy water; five patents were taken out in 1939 and 1940. On the
advance of the German forces (1940), F. Joliot managed to get the documents
and materials relating to this work transported to England. During the French
occupation he took an active part in the Resistance; he was President of the
National Front and formed the French Communist Party. After having been Director
of the Centre National de la Recherche Scientifique (1945), he became the first
High Commissioner for Atomic Energy (1946); he directed the construction of
the first French atomic pile (1948). He was relieved of his duties in 1950 for
political reasons. While still retaining the control of his laboratories, F.
Joliot-Curie took a considerable part in politics and was elected President
of the World Peace Council. On the death of Irene Joliot-Curie, in 1956, he
became, while still retaining his professorship at the Collège de France,
holder of the Chair of Nuclear Physics which she had held at the Sorbonne.

F. Joliot was a member of the French Academy of Sciences and of the Academy
of Medicine. He was also a member of numerous foreign scientific academies and
societies, and holder of an honorary doctor's degree of several universities.
He was a Commander of the Legion of Honour. His recreations show him as a man
of wide attainments, among which piano playing, landscape painting and reading
(particularly Kipling), were predominant.

Joliot devoted the last two years of his life to the inauguration and development
of a large centre for nuclear physics at Orsay. He died in Paris in 1958.

Jean Frederic and Irene Joliot-Curie had one daughter, Helene, and one son,
Pierre.
